[pstricks] Producing good PNG files

[Kin Mye]

Hi.
I am very interested on this topic, both to publish in the web and to port
figures to ms-word documents.

For the moment I use the latex2png script, included in the latex2rtf
package.

Given a document, test.tex
\documentclass{article}
\usepackage{pstricks}
\pagestyle{empty}
\begin{document}
\begin{pspicture*}(6,6)
  \psline(1,1)(5,5)
...
   \end{pspicture*}
\end{document}

Then
latex2png -d 600 test.tex
(It produces test.png with 600 dpi)

Internally, this is what latex2png does:

 latex --interaction batchmode test
 dvips -q -l 1 -E -R -o test.tmp.eps test.dvi
 eps2eps test.tmp.eps test.eps
 convert -crop 0x0 -depth 24 -units PixelsPerInch -density 600x600 test.eps
test.png


The script pst2pdf proposed by Herbert doesn't work for me.
This is what pst2pdf test.tex produces:

! Undefined control sequence.
<recently read> \c at lor@to at ps

l.9   \psline(
              1,1)(5,5)
